Definitions
- thermoplastic pipe which permits the continued use of known coupling connectors when desired or necessary.
- FIG. 4 is a longitudinal cross-sectional view of the plastic pipe, coupling connector and integrally joined locking plug.
- the plugs 22, 23, 24, while soft, are compressed slightly causing compression against sleeve 14 which, in turn, creates an annular bead 22A, 23A, 24A, respectively, which locks plugs 22, 23 and 24 into fixed relation with sleeve 14.
- the number of plugs is dependent primarily on the size of the plastic pipe to which the connector sleeve is to be affixed. On pipe sizes up to approximately 3 inches (7.6 cm), two buttons, diametrically opposed, is sufficient. Pipe sizes between 3 and 6 inches (7.6-15 cm) would be connected to connector sleeves by using three plugs. Six inch (15.2 cm) diameter and greater pipes would require four plugs, or perhaps for very large sizes even more.
- connection formed by the invention disclosed above is simple, lightweight, easy to form and yet results in a much stronger and reliable connection than has heretofore been possible.
